Abstract:
Additive manufacturing (AM), also known as 3D printing, has gained significant interest due to the freedom it offers in creating complex-shaped and highly customized parts with little lead time. However, a current challenge of AM is the lack of geometric accuracy of fabricated parts. To improve the geometric accuracy of 3D printed parts, this paper presents a three-dimensional geometric compensation method that allows for eliminating systematic deviations by morphing the original surface mesh model of the part by the inverse of the systematic deviations. These systematic deviations are measure

Abstract:
SummaryThe average effect and average excess both measure the phenotypic effects of gametes in a population. A matrix notation is introduced that provides a general analytical solution for the average effects at a single locus with k alleles that can be solved for any population regardless of its genotype frequencies. This same notation also provides an easy way of deriving and generalizing to k alleles the well-known relationships between average effects and average excesses that exist under random-mating and regular deviations from Hardy–Weinberg equilibrium due to inbreeding.

In the context of a time series, the sample mean is a time average.

Abstract:
AbstractThis chapter analyzes income data from 194 cities in 14 countries to provide an overview of residential segregation patterns in a comparative perspective. We use the dissimilarity index to measure segregation between lower income households and middle-income and higher income households. The results expand results consistent with existing research to a larger number of countries. Higher income households segregation from lower income households is significantly higher than for middle-income households. High-inequality cities are more segregated, on average, than low-inequality ones. It is in the deviation from these patterns, however, that the analysis contributes to a comparative research agenda. It highlights cities and countries that do not fit general trends and raises questions about the relative role of national and local factors in influencing levels of segregation, questions the case studies delve into in the rest of the volume.

Abstract:
Abstract This book chapter dicsusses the data, methodological strategies, and findings, and the final section concludes with a discussion of key policy implications and directions for future research regarding climate change, livelihoods, and domestic violence in Indonesia. This study argues that climate shocks in Indonesia elevate the incidence of domestic violence via their impact on agriculture and agrarian livelihoods. Those relying on agriculture as a primary income source in Indonesia-approximately 41% of the population=suffer when climatic stress diminishes earnings through job loss and reduced crop yields. The impact can reduce food security, especially for subsistence farmers, but also for the broader population when scarcity elevates local food prices. Food already consumes 70% of household budgets for half the population, with rice comprising the largest share-over 25% of total household expenditures for the poorest quintile. Thus, even minor reductions in yields or inflation in local rice markets can have dire effects. These impacts are anticipated to exacerbate social and psychological pressures-stress, anxiety, depression, trauma, substance abuse-commonly associated with domestic and intimate partner violence, which in turn should increase its incidence within affected regions. This study uses data from the Global SPEI database and the NVMS to model the relationship between climate change and domestic violence in Indonesia. It finds that positive and negative deviations from long-term climate averages, when occurring in December-the core month of the Indonesian rice-planting season-increase the incidence of domestic violence in the following year. This relationship likely reflects the negative impact of climate shocks on agricultural sectors and livelihoods, an outcome which aggravates the emotional and psychological preconditions for domestic violence and abuse, disproportionately diminishes women's bargaining power in the household, and reduces women's ability to escape abusive situations. These effects are especially prominent in areas with higher levels of poverty, further illustrating the economic dimension of the causal process.

Abstract:
Injection molding process is increasingly more significant in today’s plastic production industries because it provides high-quality product, short product cycles, and light weight. This research optimizes the performance of this process with three main quality responses: defect count, cycle time, and spoon weight, using the weighted additive goal programming model. The three quality responses and process factors are described by appropriate membership functions. The Taguchi’s orthogonal array is then utilized to provide experimental layout. A linear optimization based on the weighted additive model in goal programming model is built to minimize the deviations of the product/process targets from their corresponding imprecise fuzzy values specified by the process engineer’s preferences. The results show that the average defect count is reduced from an average of 0.75 to 0.16. Moreover, the average cycle time becomes 13.06 seconds, which is significantly smaller than that obtained at initial factor settings (= 15.10 seconds). Finally, the average spoon weight is exactly on its target value of 2.0 gm.

Abstract:
• To understand the concept of mean, variance, and standard deviation pertaining both to a large sample (population) and a small sample. • To define the standard deviation of the mean of a number of repeated measurements and understand its relation to the sample standard deviation. • To define confidence intervals about a mean and show how to use them to indicate measurement precision. • To introduce robust estimators of representing the average and sample standard deviation. • To appreciate the difference between measurement repeatability and reproducibility…. Why do we bother with means and standard deviations? Because these two statistics tell us a great deal about the data and the population from which they come. A mean of a number of repeated measurements of the concentration of a test solution is an estimate of the concentration of the test solution and the sample standard deviation gives a measure of the random scatter of the values obtained by measurement. Together with the appropriate units they represent the result. This information is not necessarily the answer to: ‘‘What is the concentration of the test solution and how sure are you of that answer?’’ To answer this question an uncertainty budget must be prepared, which includes errors, random and systematic, arising from all aspects of the experiment (of which the standard deviation of repeated measurements is just one). Why is it good to repeat analytical measurements? There might be an argument for the ‘‘quit while you are ahead’’ school but repeating a measurement gives increased confidence in the result, especially if the numbers appear to agree. But apart from the appearance of consistency, do you get better answers by repeating measurements, and are more repeats better than fewer repeats? The answer to both questions is ‘‘yes,’’ as we shall see in this chapter. Note that the statistical treatment of repeated results does not tell us about systematic error unless we can compare our mean with a known or assigned value of the quantity being measured.

Abstract:
The atoms in a crystal are vibrating with amplitudes determined by the force constants of the crystal’s normal modes. This motion can never be frozen out because of the persistence of zero-point motion, and it has important consequences for the scattering intensities. Since X-ray scattering (and, to a lesser extent, neutron scattering) is a very fast process, taking place on a time scale of 10−18 s, the photon-matter interaction time is much shorter than the period of a lattice vibration, which is of the order Thus, the recorded X-ray scattering pattern is the sum over the scattering of a large number of 1/v, or ≈10−13s. instantaneous states of the crystal. To an extremely good approximation, the scattering averaged over the instantaneous distributions is equivalent to the scattering of the time-averaged distribution of the scattering matter (Stewart and Feil 1980). The structure factor expression for coherent elastic Bragg scattering of X-rays may therefore be written in terms 〈ρ(r)〉, of the thermally averaged electron density: . . . F(H)=∫unit cell〈ρ(r)〉 exp (2πi H ·r) dr (2.1) . . . The smearing of the electron density due to thermal vibrations reduces the intensity of the diffracted beams, except in the forward |S| = 0 direction, for which all electrons scatter in phase, independent of their distribution. The reduction of the intensity of the Bragg peaks can be understood in terms of the diffraction pattern of a more diffuse electron distribution being more compact, due to the inverse relation between crystal and scattering space, discussed in chapter 1. The reduction in intensity due to thermal motion is accompanied by an increase in the incoherent elastic scattering, ensuring conservation of energy. In this respect, thermal motion is much like disorder, with the Bragg intensities representing the average distribution, and the deviations from the average appearing as a continuous, though not uniform, background, generally referred to as thermal diffuse scattering or TDS. A crystal with n atoms per unit cell has 3nN degrees of freedom, N being the number of unit cells in the crystal.

However, TET is not uniform at the turbine outlet and the temperature is therefore sometimes measured at several axial and radial positions. The TET has what can be considered a natural variation, an effect of operation in different ambient and operational conditions which influences the internal flow field. It can be informative on the healt

Abstract An enhanced process to Ansaldo Energia Switzerland’s validation approach for vibrational behaviour of gas turbine compressor blading is investigated. The opportunity of relying on less and early-stage measurements is assessed as a driver for cost and time optimisation. Accordingly, an analysis of possible variations of measurement data available during all validation phases is performed in order to confirm observed and expected correlations on a large scale, facilitating measurement chain improvement and simplification. Profile deviation and frequency distribution analysis finds the p

Abstract:
Solar radiation data have been acquired over approximately a five year period (1996 to present) at 15 sites in Texas (Texas Solar Radiation DataBase – TSRDB). These data are compared with comparable sites in the National Solar Radiation DataBase (NSRDB). Comparison of the TSRDB and NSRDB data for eleven (11) coincident or nearby locations show reasonably good agreement between the global horizontal values. Relative to the NSRDB, individual monthly average differences between the two sets range from −20 to +13%, and the annual averages varied from −9 to +8.5%, with positive values meaning the T

Abstract:
The pressure drop and heat transfer characteristics for partially-confined heat sinks with different fin types, including plain-plate fin, pin-fin array and strip-fin array, in ducted flow are investigated. The main focus of the experimental results is on pressure drop and heat transfer characteristics of generalized heat sink in ducted flow with considering the flow top- and side-bypass effects. The parameters controlled in the study are the heating load (Qt), inlet flow velocity (Ui), the ratio of heat sink height to duct height (Hs/Hc), and the ratio of heat sink width to duct width (Ws/Wc)

Abstract:
Uruguay has increased it preschool enrollment, reaching almost universal coverage among four- and five-year-olds. However, more than a third of children enrolled in preschool programs have insufficient attendance, with absenteeism higher in schools in lower socioeconomic areas and among younger preschool children. This paper presents the results of a behavioral intervention to increase preschool attendance nationwide. Most previous experiments using behavioral sciences have looked at the impact of nudging parents on attendance and learning for school-age children; this is the first experiment

We conducted an experiment in low-income schools in Chile to test the effects and behavioral changes triggered by a program that sends attendance, grade, and classroom behavior information to parents via weekly and monthly text messages. Our 18-month intervention raised average math GPA by 0.09 of a standard deviation and increased the share of students satisfying attendance requirements for grade promotion by 4.5 percentage points. Treatment effects were larger for students at higher risk of later grade retention and dropout. Leveraging existing school inputs for a light-touch, cost-effective

The goal of this paper is to document the pedagogic impacts of the remote learning strategy used by an state department of education in Brazil during the pandemic. We found that dropout risk increased by 365% under remote learning. While risk increased with local disease activity, most of it can be attributed directly to the absence of in-person classes: we estimate that dropout risk increased by no less than 247% across the State, even at the low end of the distribution of per capita Covid-19 cases.
